From the reviews

This gym is tremendous. I was in town for work and Jamie was teaching the 5:30 am class and welcomed me immediately like I was a great addition to class. He is a gifted teacher and he is so attentive to his students. It’s clear that he’s vested and cares a great deal for everyone in class - even a guest like me.

★★★★★ — Chad, Mar 2023

I went into J3 for the first time knowing nothing about jiu jitsu nor did I know anyone there or anyone who even did jiu jitsu. That is intimidating by itself. But Jamie and Ryu were the first two people I met, and they made me feel very comfortable and excited to get started.

★★★★★ — Juliette, Aug 2017

J3 is an amazing community of humble hearted and generous martial artists. The environment is always welcoming and the coaches and professor Jamie are always pouring into the students to improve.

★★★★★ — Jacob, Jul 2024

Even though we pass several other schools on our way here, we wouldn't take our son anywhere else. Professor John is truly amazing with my 4-yr-old and the rest of the class. He knows how to keep the attention of kids at this age group and is also very talented with martial arts.

New to muay thai? Start at J3 Jiu Jitsu Academy

J3 Jiu Jitsu Academy comes up as a beginner-friendly gym, going by their listing and members’ reviews. If you've never thrown a punch or a kick, that's exactly who a good beginners program is for. A few things worth knowing before your first week. First, you don't need to be fit to start — you get in shape by training, not before it, and coaches scale the conditioning to you. Second, you won't be thrown into sparring — reputable gyms build fundamentals (stance, footwork, and the basic strikes of the "art of eight limbs") for weeks before any contact, and sparring stays optional. Third, all levels really are welcome — ask about a dedicated beginners or fundamentals class time so your first session is alongside others who are also starting out. Most gyms are happy to let you watch or try a class first, so reach out before you commit.

Your first muay thai class at J3 Jiu Jitsu Academy

Nervous about walking into a muay thai gym for the first time? Almost everyone is, and good coaches expect beginners to come through the door. Here's what to know. What to expect: a typical first class is a warm-up, then drilling the basics on pads and bags — not fighting. Rest whenever you need to; no one will bat an eye. What to wear: shorts or athletic wear and a t-shirt; you'll train barefoot on the mats. What to bring: water and hand wraps if you have them — many gyms lend gloves for a first class, so it's worth asking when you call. As you keep training you'll add your own gloves, wraps, a mouthguard, and shin guards. Sparring is optional and comes later, once your fundamentals are solid. Arrive 10–15 minutes early to sign a waiver and meet the coach. It gets easier fast — most people feel far more at home by their third class.

Muay thai is a contact sport. Ease in, listen to your coaches, and if you have any injuries or health concerns, mention them before class and check with a doctor if you're unsure.
